| 20080198357 | Optical navigation device and method thereof - An optical navigation device and a method thereof, wherein the optical navigation device comprises a pair of linear sensor arrays which are arranged non-parallel to each other for detecting light signal. Furthermore, an algorithm including correlation and vector analysis is processed by a computation unit to determine velocity and displacement according to present and previous light signal data sequences. Hence, the linear sensor arrays adopted to be the approach of navigation device can achieve the goal of reducing the computing data, increasing operation speed effectively and reducing hardware cost because of its fewer optically sensitive elements. | 08-21-2008 |

| 20100097706 | Optical sheet - An optical sheet is adapted for diffusing and converging light, and includes a light-transmissive base layer, a prism layer, and a plurality of diffusion regions. The base layer has a first surface and a second surface that is opposite to the first surface. The prism layer is provided on the first surface of the base layer and has a plurality of prisms, each of which has a peak and two inclined surfaces that meet at the peak. At least two of the peaks of the prisms are different in height. The diffusion regions are disposed on the inclined surfaces of the prisms. Each of the diffusion regions is in the form of a roughened surface. | 04-22-2010 |
| 20110038052 | Prismatic Laminate and Method for Making The Same - A method for making a prismatic laminate includes the steps of: a) forming a back-coating roller having a roller surface with a plurality of recesses arranged in a predetermined pattern and produced by laser holography; b) preparing a prismatic structure including a plate body having a first surface and a second surface opposite to the first surface, and a plurality of prismatic strips formed on the first surface of the plate body; c) applying a coating containing a resin component and an antistatic agent on the second surface of the plate body; and d) embossing the coating with the back-coating roller to form an optical layer including a plurality of microstructures protruding in a direction away from the second surface of the plate body and having a pattern corresponding to that of the recesses in the roller surface. | 02-17-2011 |
